Hello all, the purpose of this guide is purely for sharing and referential purposes and largely aimed at similar variants of this notebook. However, I do not guarantee it'll give you the exact compatibility as with any OEMs, products can be marketed under the same model while its components can come in different revisions with slight changes take the reference as a guide only at your own risk.

Reason: Get rid of bloat and OEM customisation in case it conflicts with the eGPU setup.

Spoiler

If you would like to use a generic version of Windows 7, backup your the entire of the following directory to an external disk. It contains every single stock driver required for your PC. Including Switchable Graphics driver if your model has an AMD dGPU.

C:SWsetup

Reminder: Backup your important stuffs, they will be wiped from the HDD/SSD. Also create the recovery image (HP stock recovery) with DVDRs or CDRs.

While installing Windows 7 via a USB image, make sure you plug in the USB drive to a USB 2.0 slot. Not the USB 3.0 slot on your laptop because SandyBridge systems cannot run USB 3.0 natively without drivers. For your activation code, its the OEM product key on the sticker below your laptop.

To install the drivers on the generic Windows 7:

Start

Type "device manager"

Point all devices with an "!" to the directory of the external drive containing the full SWsetup folder

IMPORTANT: If your notebook has an AMD dGPU, DO NOT install a reference Intel HD driver from Intel's website stick with the stock Intel HD driver by HP. You have been warned...

Your AMD GPU (i.e. 6490M, 6470M, 6770M) will stop working without the presence of the factory Intel HD driver provided by HP whenever you need to unplug your eGPU. Reason's because hybrid graphics (Enduro) is not built into the AMD dGPU driver at least with the 6000M series. The implementation partially relies on a custom Intel HD driver supplied by HP.

You may only use Intel reference drivers if you have no AMD GPU. I'm stressing on this point.

Before You Start

Login to your admin account.

Disable User Account Control (Slider all the way down). Search for it from the start menu search tool.

Software Installation Instructions

For users who want to reverse the order of the Windows bootloader to let the first option be Setup 1.x instead of Windows 7, use a tool like EasyBCD.

The countdown timer can also be lengthened/shortened with this tool.

It also looks like the PCI space requirement for the GTX650Ti Boost *could possibly* be following its bigger brother, GTX660 since it is an almost full featured GK106. Unlike the rest of the GTX650 series (650/650Ti non-boost). Installation encountered no issues at all.

Tested only benchmarks and Crysis 2 so far. Crysis 2 was buttery smooth on extreme preset.

Edit: Thanks for the formatting chmod

PS @ Nando4, HP's Sandybridge model doesn't include a DV4. Dm4 is the exact 2011 replacement for the DV4 series in 2011. (very similar to DV6-6000 & DV7-7000 internally and externally)

Lots of similar HP consumer SB/IVB notebooks sold. Thank you for this important post giving those owners a documented way of improving their GPU performance via a mPCIe-based (wifi) DIY eGPU implementation.

Are your benchmark results using the internal LCD or external LCD? External is faster since the display data isn't being shuttled across the x1 2.0 pci-e link for display back onto the internal LCD. The reference benchmarks on the main DIY eGPU experiences thread are using an external LCD.

Do you any photos of your experiment to share? Brings the whole thing to life

Benchmarks are internal LCD I'll try get that on some time after. My eGPU is dismantled atm because my desk is lacking space and I need it for something else. Noted that, I'll experiment with the external LCD (900p) when I'm ready. Got no idea on the performance level I'll be expecting. I'll be taking some pics too

Edit: I forgot that I lost my DVI cable a long time ago... Probably I'll try finding it.

Btw for best performance on an external monitor, simply plug in the DVI cable to the eGPU? Do I have to switch anything related to primary and secondary monitors via Windows display settings?

To use the external LCD right click the desktop, select Screen Resolution, ensure the external LCD is detected and check "Make this my main display" like shown below. Your Start menu will then appear on the external LCD and launching apps there will use that LCD and underlying eGPU.

Hi everyone,
I'm newbie here so if I'm posting somewhere wrong or smth like that just warn me.

I search in this forum and also at google about "code 12" and "code 43" almost thousands times. Specially for exp gdc but couldn't find anything can help me. I looked for modded bios, whitelist.. At least I realized that there is no modded bios for my pc(I'm gonna write all supported bios versions down here). All cable connections are correct, I can see Nvidia GTX 1070 at device manager with error code 12 and sometimes code 43.

I couldn't disabled my amd redeon graphics in bios, just uninstalled from device manager with files. Now my pc running only with Intel HD 3000 by own screen. I do not get any display on my 24" screen which one is connected to 1070 by HDMI. But when I boot my pc, 1070 fans are running with white lights are on GPU. But screen display doesn't show anything. Pc running with own screen.

Exp gdc connected by m-pci/e.
I have 350W PSU just for GPU.(170W needed)

I tried to install nvidia driver, remove amd by DDU, run only 1x8gb ram(tried at both slots), remove wifi adapter from device manager with files,
Anyone can help me about how to get result-fix this issue. There is no problem to disable pc own 15.6" screen. Just want to run my pc with good screen by 1070.

Hey guys, just got my GDC Beast V8 in yesterday and put my eGPU setup all together. I know my PSU works and I know my GPU works (tested in another machine). My HP laptop has whitelist, so I tried booting with my wifi card, putting computer to sleep, hotplugging mPCIe adapter in, and turning the computer back on - but windows doesn't detect the GPU. I've also bought DIY eGPU Setup and hotplugged whilst in that, and even then the GPU doesn't register. I tried doing the same on another (Dell Inspiron 1420) laptop, with the same results. I can't figure out what is wrong, short of the HDMI to mPCIe cable being bad. But it doesn't seem bad since the GPU/PSU turn on/off when I turn my laptop on/off.

Further, I've tried taping over pin 22, as well as hotwiring the PSU to be always on before hotplugging the adapter into my mPCIe port. Still no luck.

Are there more settings I need to be changing in DIY eGPU Setup, such as link speed or width? I really thought hot plugging was the defacto tell on whether or not your setup works or not. Thanks for your help!
